What are the reasons for a vehicle pulling to one side while driving?

Reasons for a vehicle pulling to one side while driving: 1. Uneven road conditions - ordinary flat roads are designed with a higher center and lower sides; 2. Inconsistent tire pressure - unbalanced tire pressure on both sides; 3. Uneven tire wear - vehicle tires should be rotated regularly as drive wheels wear faster than others, and inconsistent tread wear on both sides can cause pulling; 4. Damage to chassis suspension components such as bent steering knuckle arms, deformed shock absorbers, or loose lower control arm ball joints; 5. Excessive mileage causing changes in wheel alignment parameters due to poor road conditions; 6. Unqualified repair parameters after accidents, including inconsistent wheelbase lengths on both sides or improper correction that doesn't meet technical requirements.
Having driven for over a decade, I know that car misalignment is no small matter. The most common issue is tire problems—when the tire pressure on both sides is uneven, the car will pull toward the side with lower pressure, or uneven tire wear can cause misalignment due to reduced friction on the more heavily worn side. The suspension system is also crucial; damaged shock absorbers or deformed control arms can affect balance. Misalignment is the most frequent issue, such as incorrect toe angle or camber angle causing the steering wheel to be off-center. If the braking system drags on one side, it can also cause pulling, especially noticeable when going downhill. Additionally, chassis damage or road tilt can be contributing factors. For safety, get it checked as soon as you notice the problem. Regular wheel alignment and tire pressure monitoring can help prevent these issues.
